Alright, I'm not sure if it is a problem or not, but just got a brand new Nightforce ATACR 5-25x56. When I am rotating the parallax knob it is not completely smooth for the entire revolution. There are spots where it slightly rougher than the other areas. Seems to be most prevalent when going from for instance 500yds back down to the closest setting. Its not terribly rough, but it definitely changes feeling in that area. Am I just being picky or am I feeling a problem. By the way the scope isn't and hasn't been mounted. Thanks in advanced!!
